Re: User Space question

I SO much prefer using the pointer method! Once you get past thinking
pointers are some sort of tool of the devil it is so much easier.

For example, let's say IBM announced the rNext of the OS would no longer
support simple addition in RPG. Any new compiles would have to replace
x=y+z;
with
x=PerformAddition(y : z : '1' : ErrCde);
where the third parameter was whether or not to allow truncation if the
sum of y + z was greater than the size of x, and the fourth parameter was
the standard error code.
Wouldn't that be nuts?
Then why would anyone prefer calling QUSCHGUS over
myChar char(10) based(pmyChar);
...
for x = 1 to ListNumber;
pmyChar=Initial + (OffsetSize * x);
dsply myChar;
EndFor;

Look at QUSCHGUS's parameter 5 - Force changes to auxiliary storage


Force changes to auxiliary storage
INPUT; CHAR(1)
The method of forcing changes made to the user space to auxiliary storage.
The valid values are as follows:
0

Does not force changes. Normal system management writes the changes to
auxiliary storage.

1

Forces changes asynchronously. This interrupts the normal system
management and ensures that the user space is written to auxiliary
storage.

2

Forces changes synchronously. This interrupts the normal system management
and ensures that the user space is written immediately to auxiliary
storage.




Or use a pointer to the space (QUSPTRUS api). Obtaining a pointer to the
user space will provide virtually immediate update when the value for the
space is changed.

Subject: User Space question



This past week our UPS failed, as a result the building lost power and the
iSeries (720 , with V7R1) immediately shutdown.



The only "fall out" has been related to several user spaces that we use as
"next sequential" number counters.



The value of the user spaces when the system came back up did not reflect
updates that had occurred during the day, and as a result various files
had duplicate "sequential" numbers.



My question, is there a function for a user space that is similar to
FRCRATIO for a database file?



TIA
